Patent number: 7928333Abstract: A device, such as a switch structure, is provided, the device including a contact and a conductive element. The conductive element can be configured to be selectively moveable between a non-contacting position, in which the conductive element is separated from the contact (in some cases by a distance less than or equal to about 4 ?m, and in others by less than or equal to about 1 ?m), and a contacting position, in which the conductive element contacts and establishes electrical communication with the contact. When the conductive element is disposed in the non-contacting position, the contact and the conductive element can be configured to support an electric field therebetween with a magnitude of greater than 320 V ?m?1 and/or a potential difference of about 330 V or more.Type: GrantFiled: August 14, 2009Date of Patent: April 19, 2011Assignee: General Electric CompanyInventors: Xuefeng Wang, Marco Francesco Aimi, Shubhra Bansal, Christopher Fred Keimel, Kuna Venkat Satya Rama Kishore, Kanakasabapathi Subramanian
